### What should this feature add?

In comfy UI we have the FluxKontextImageScale node due to Kontext prefers the following sizes, as referenced in this file: https://github.com/comfyanonymous/ComfyUI/blob/d9277301d28e732e82d0de1d5948aa00acbf6b65/comfy_extras/nodes_flux.py#L81

"PREFERED_KONTEXT_RESOLUTIONS = [
(672, 1568),
(688, 1504),
(720, 1456),
(752, 1392),
(800, 1328),
(832, 1248),
(880, 1184),
(944, 1104),
(1024, 1024),
(1104, 944),
(1184, 880),
(1248, 832),
(1328, 800),
(1392, 752),
(1456, 720),
(1504, 688),
(1568, 672),"

It would be a nice addition to add those resolutions to invoke's optimize size for model feature, however it currently always resets the resolution to 1024x1024 it would be nice to click this button and invoke automatically resizes to the closest or show us more sizes if right clicked.
